“…It can be used in many applications, such as solar cells, catalysts, sensors, and photodetectors. Few studies have recently investigated how combining PbS with other active materials increases PbS’s energy storage performance [ 22 , 23 , 24 , 25 , 26 , 27 , 28 , 29 ]. For example, Cheol-Hwan Mun et al synthesized a NiS-PbS composite that exhibits a higher specific capacity of 125.89 mA h g −1 at a current density of 2 A g −1 [ 22 ].…”

In this work, a polyaniline/lead sulfide (PANI/PbS) nanocomposite was prepared by combining the in situ oxidation polymerization method and the surface adsorption process. This nanocomposite was applied as a supercapacitor electrode. The crystal structure, nanomorphology, and optical analysis of PANI and PANI/PbS were investigated. The electrochemical performance of the designed PANI/PbS electrode-based supercapacitor was tested by using cyclic voltammetry (CV), chronopotentiometry (CP), and AC impedance techniques in HCl and Na2SO4 electrolytes. The average crystallite size of the PANI/PbS nanocomposite is about 43 nm. PANI/PbS possesses an agglomerated network related to PANI with additional spherical shapes from PbS nanoparticles. After the PANI/PbS nanocomposite formation, there are enhancements in their absorption intensities. At a current density of 0.4 A g−1, the specific capacitance of PANI/PbS in Na2SO4 and HCl was found to be 303 and 625 F g−1, respectively. In HCl (625 F g−1 and 1500 mF cm−2), the gravimetric and areal capacitances of the PANI/PbS electrode are nearly double those of the Na2SO4 electrolyte. Also, the average specific energy and specific power density values for the PANI/PbS electrode in HCl are 4.168 Wh kg−1 and 196.03 W kg−1, respectively. After 5000 cycles, the capacitance loses only 4.5% of its initial value. The results refer to the high stability and good performance of the designed PANI/PbS as a supercapacitor electrode.

“…Though there is lack of information about how leaf-like structures grow, certain growth on specific planes may direct the final shape of the structures. For instance, dendritic fern-like structures based on rGO/BiVO 4 61 and fractal fern-like structures based on PbS 62 were successfully synthesized through a hydrothermal method. As reported by Dai et al , 62 such formation of fractal fern-like structures was possible based on the rapid nucleation of PbS to form small crystallites.…”

These crystallites further grew along the 〈111〉 direction of the {111} close-packed plane because PbS has a face-centered-cubic structure, and thus resulted in a fern-like architecture 62 (Fig.…”
